Original Abstract

Materials like concrete are widely used for civil engineering constructions, due to some well-known benefits such as low cost, wide applicability, and general availability. The structural part is usually loaded in combined load referred as mixed mode (normal mode I and shear mode II). Generally, concrete, the quasi-brittle material, gets more brittle as its strength increases. The experiments already measured on civil engineering materials were analysed by the mixed-mode crack growth criteria based on the fracture toughness KIc (critical energy release rate GIc), it follows that different authors very extensively and variously use this concept. The criteria applied in the contribution are based on the parameters stress intensity factor K and energy release rate G. The value of Keff based on material fit and index of dispersion were discussed and compared for material with different compression strength.
